Haachi
A Haachi is the worst kind of guy, part athlete, part cheater, part gay, part dumbass, and still thinks he's the best at everything.
My gym teacher called me a Haachi for cheating on my test and then asking me out.
That guy is a Haachi, he vapes, flirts with everyone, and still can't do a single sit-up.
My cousin got called a Haachi for copying my answers and then cheating on his girlfriend.
